Lab-Grown Diamonds: Everything You Need to Know Before Buying in 2025


The diamond industry is experiencing its biggest transformation in over a century. Lab-grown diamonds now represent 20% of the global diamond market, and that number is climbing fast. Whether you're shopping for an engagement ring, anniversary gift, or simply curious about this revolutionary technology, this comprehensive guide will give you everything you need to make an informed decision.

Lab-Grown Diamonds

What Are Lab-Grown Diamonds, Really?

Lab-grown diamonds are real diamonds—chemically, physically, and optically identical to mined diamonds. The only difference? They're created in controlled laboratory environments rather than deep within the Earth over billions of years.

Two main production methods exist:

CVD (Chemical Vapor Deposition): Carbon atoms are deposited layer by layer onto a diamond seed

HPHT (High Pressure High Temperature): Mimics the extreme conditions that create natural diamonds underground

What Are Lab-Grown Diamonds

Both methods produce genuine diamonds with the same hardness (10 on the Mohs scale), brilliance, and fire as their mined counterparts.


The Numbers Don't Lie: Market Growth & Consumer Demand
